Systems and processes for measurement of the eyelid movements of a subject, which explores eyelids electrical conductivity, namely the established fact that eyelids are acting as sliding electrodes moving over the cornea, is comprised of a system for generating a high frequency weak and harmless oscillating electromagnetic field in the proximity of the eyelid movement path without interference with the vision or activity of any such subject, therefore induces so-called Eddy Currents in the eyelid, which in its turn produce its own electromagnetic field with a value depended on the eyelid position the interaction between the basic oscillating electromagnetic field and the field generated by the eyelid is changing electromagnetic field inductance, which will be measured with very high accuracy by means of resonance sensing electronics such systems can transmit data from its detecting electronics to a remote monitor that compels no restrictions on operator activity.
